mnelab: MNE Qt Browser does not work with MNELAB

I’m using MNE 1.5.1 and MNELAB 0.8.6 with the [full] installation on a windows 11 workstation. I’ve loaded .vhdr and .fif files and can plot PSD and inspect channels in what looks like the normal qt windows. But I get the following error when trying plot data: Traceback (most recent call last): File "C:\Users\moberg\AppData\Local\mne-python\1.5.1_0\Lib\site-packages\mnelab\mainwindow.py", line 783, in plot_data win = fig.canvas.manager.window ^^^^^^^^^^ AttributeError: 'MNEQtBrowser' object has no attribute 'canvas' Also, after this error the toolbar icons are replaced with text description (that get cropped with ellipses … ) What do I need to look into for trouble shooting?

Yes I think resources is how we do it in MNE-Python and IIRC it’s not too difficult

Probably yes, I am not a QT specialist, something like this on mne-qt-browser side might help ‘QIcon.setThemeSearchPaths([local_icon_dir]

QIcon.themeSearchPaths())’

This is very helpful @danieltomasz https://github.com/danieltomasz! I think MNE Qt Browser should not overwrite existing search paths then, WDYT?

Regarding the default settings, I think this is a separate issue which also applies to the Matplotlib backend. I’m fine with changing it to e.g. 20 channels per page and auto-scaling. Can you create a new issue?

Nice find @danieltomasz! I’ll pin PySide6 and then release a quick hotfix, ideally together with #403.

I can confirm that downgrading on MacOS 14.3.1 helps with crash and it gives the other expected error AttributeError: 'MNEQtBrowser' object has no attribute 'canvas'

After removing mne-qt-browser from my env dependencies and and pinning PySide6 to 6.5.3 I can plot raw file (with mnelab 0.8.6 on MacOS)
